"24 Dec, 1919; Norway, 30 Dec, 1919 Germany, 10 Ju11e,'1920; and I do hereby de clare the following to be a full, clear, and eXact descriptionof theinvention, such as will enable others skilled in the art to which it appertains to inalieand use the same.

The present invention has reference to an hydraulic motor arranged to utilize the live force of a river or stream withoutha'ving recourse to dams or other similar means for the retention of water.

The accompanying drawings, which represent diagrammatic views, will enable it'to be understood how the invention can be utilized practically.

In the drawings:

Fig. 1 is an elevation of a complete plant comprising the motor and its transmission gearing or shafting.

Fig. 2 is a plan View of the same installation.

Fig. 3 is a diagrammatic view of a modifieation of the motor. 9

Fig. 4.- shows a complete group of coupled motors.

Fig. 5 shows a method of construction of the rotors or turbine.

' At the end of a pair of lever arms or supports comprising frame 10 adapted to oscillate by means of a shaft 5 in bearings 11 placed on the top of monolithsor pillars 88 lodged or bedded upon thesteep bank of a river or watercourse, two rotors or turbines 1 and 1 of special form are mounted, of which mention will hereinafter be made.- These rotors are rigidly attached to a shaft 2 rotating in bearings of a suitable type mounted upon the lower end of the frame 10.. Upon this shaft there are keyed transmission pulleys 3-3 which, by means of a chain or other suitable device, impart their movement of rotation to the pulleys 4-4 keyedupon the shaft 5. On the extensions of this shaft, on the outside of, or beyond the bearings 11 are keyed pulleys 6-6 two on each side in Specification'ef Letters Patent. Patented Apr, 18, 1922;

the example given, which serve to operate 7 dynamos 7-7by means of belting or other suitable transmission. Upon the transoi-ns, which connect the upper ends of the lever arms or supports of the fraine'lO, there is a hook 12 around which is passed a chain 7 adapted to be wound up on a winch 9. This arrangement permits of the re,'g'ul'ation of the immersion of the rotors in the river. The whole of the shaftings and 'dynamos could, of course, be 'inclosed in a hall. or chamber not shown in the drawings. The transmission gear to the dynamos is'merely given by way of example but, as will readily be understood, the force or energy may be utilized 'in any suitable manner The rotors, forming the obje'ctoif the invention, comprise a cone of revolution with. a generatrix curv e,at the base of which there is fixed a certain number of vanes, the number of which will depend upon the results -which it is desired to obtain with a current having a given speed.

The apex or POHlt of the cone is of course should give good results it is necessary that the distance of the down-stream rotor should be sutficiently large in relation to that of the Lip-stream rotor, the vanes being of theradiating or slightly curved type.

If desired, and provided the width of the river or watercourse permits of it, two rotors 1 and 1 at a slight distance from each other may be placed on the supporting frame 10 as shown inFig. 3 and, also if desired, as many as three could even be used.

The regulation of the depth of immersion of the rotors could, as will be apparent, be also effected automatically assuming that conditions are such as to obtain constant work. It will even be well to be able to cause the rotors to be entirely withdrawn from the water should work be intermittent or in event of repairs being necessary. If, in certain cases, the width of the canal or. the weakness of the current should not per mit of the realization of the necessary power with the arrangement described having two or four motors, it will be possible to couple with Cardan gearing to the shafts of the first arrangement, composed of four rotors 1, 1, 1,1 (Fig. 4), other shaft extensions carrying the rotors 1, 1', 1', 1', and these shafts will be supported either by floats or by transom the - resulting in anin'creased utilization of the beams 13-l3 fixed tothe bank and maintalned iii-position by means of transoms be-' tween each joint 14, of each line of hafting. Fig. 'shows a structional form of rotor comprising a cone 14: withia generatrix curve to which the vanes l5 are attached. The apex of the cone 14; is cut over a certain extent o'i itslength so as to form at 16 an aperture for the passage of the water, the result of such aperture being to break up those eddies which are formed to the rear of the The webs or radii 17 connecting the cone 14 to its base'18 are of the same general form as the wings or vanes 15 of the rotor;

Water current, the said radii adding their effect to that of the vanes of the motor.

The vanes 15 which, of course, always form a part of the cone 14, are not placed,

direct in its prolongation, but are attached to the periphery as clearly indicated.

a 1 Claims: r

1. In a hydraulic motor, the combination with a support, of a rotor mounted von the lower end of'said support adapted to be submerged in a watercourse, the said rotor comprising a .cone,* having a generatrix curve, a crown of vanes carried by the base of said cone adapted to be acted upon by the passing water or current of said water course for rotating said cone and means for transmitting the power generated by said rota- -tion.

' 2 In a hydraulic motor the combination with a pivoted support, of a rotor mounted on the lower end of said support'adapted to be submerged 111a. watercourse, means for regulating the submerged depth thereof; the

sage, webs or vanes formed in the interior of said cone, whereby means are prov ded to be acted upon by the water as t passes outside of and through the cone for rotating said cone and means for transmitting the power generated by said rotation.
